Speaker Box / Enclosure Specifications

This is the shape of the enclosures cutout hole and defines the style of subwoofer that can be installed.

Round / Circle

Box Type

Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.

Vented / Ported

Number of Subs/Speakers

This value represents the number of speakers or subwoofers that the enclosure accommodates.

Box Style/Shape

The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.

Square/Rectangle

Cutout Diameter or Length

The actual diameter of the hole in the subwoofer box. Length is the measured length per side of a square subwoofer or speaker opening.

This is the total air space inside each chamber of the empty subwoofer enclosure. By matching this value with the recommended air space of the subwoofer, you will be able to know if the subwoofer will match this box.

14"

Width

The width of the item from left to right (side-to-side) measured in inches.

32"

Depth

The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

Wood Thickness

The thickness of the wood the enclosure is made of, measured in inches.

Number of Terminals

The number of terminals the enclosure has. Each terminal represents 1 positive and 1 negative.

1

Terminal Type

Spring clip terminals work best with bare wire connections with small-gauge speaker wire, or pin-type connectors.

Binding post terminals are a sturdier, more versatile type of speaker terminal. Because binding post terminals are are threaded, you can tighten them down against the wire or connector for a tight, clean connection. The most popular style of binding post terminals is known as a "5-way binding post". This type can accept bare wire, or any of the common speaker wire connectors. Binding posts with the option to be used with banana clips are even more versatile

Spring posts are a hybrid of the two. Instead of using a thread and "screwing" them tight, they use a spring to allow the wire to fit and tighten against the terminal.

Binding posts

Box Exterior Color

The color of the enclosure's exterior/outer finish.

Gray

Box Finish

The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

I bought this enclosure and was disappointed. My 1500w system with two 12" subs kick so hard that the walls of the enclosure vibrate as if they are going to come out of its joints. It results in a loud vibration noise. Would not purchase again.

This box plays the notes amazingly. From high to lows, it will slap you in the face and keep coming 'til you can't take it. But like the guy before me, the walls flex as if they are goin' to blow. I have 2 Kicker CVR's in this, and the first week was great. Then, all of a sudden, I heard a vibration. So I popped my trunk, and found a line of saw dust on my trunk floor behind the sub box. Looks like the back wall was literally blowing out and creating dust where the nails are. So, I had to screw a bunch to stop the rattle, but it still bounces, and isn't very sturdy like the other walls. Very flimsy. Not too happy. Would not purchase again.

This box I knew was going to be big. but I didn't think this big, it barely fit into my trunk but thankfully it did. I put polyfill on the walls inside and it is overall a great box, very sturdy strong walls unlike the previous comments, the box looks great and my two 12'' infinities sound beautiful in it thank you sonic.
pros: great looking great sturdy box
cons: its huge

im running 1200 true watts to 2 alpine type R's the power from my subs rattled the walls loose and made a terrible noise...if you are running 500-800 watts this would be an excellent box, but its not built strong enough to handle more power than that.

I played this box for about a week when all the sudden i herd a very loud vibration.I popped the trunk and tryed to figure out what was wrong. I ended up pushing down on the box and the vibration quit. The back part of the box had been blown out of place. I cant even play the speakers anymore very disappointed. I would not recomend this box to anyone.

This box hits hard and fits my 2 12" kenwood performance subs well. I'm running a 1800w kenwood 9105D amp (900rms @ 2 ohm) to the 2 subs (400rms each). Shakes the entire car, even with sound deadener that is literally on every inch of the trunk and most of the interior. Unfortunately, the 2 terminals are poorly designed for this box I think, I had trouble with them right away, the subs shook the nuts off of the bolt holding the wire almost immediately, so if you notice any problems w/ power, check there first. Otherwise this is a great buy.

I bought this box, and I was skeptical on how they would sound with my brand new 12" Pioneer Premier Champion Pro Series subs (TS-W3002D2), and let me tell you thing things slammmm! The lows are amazing and the highs are alright. I'd say if you're looking for that deep bass with these speakers, this is the box to use. The highs don't hit extremely loud, but you can still hear them pretty well. I was looking for deep bass anyways. Talk about severe trunk rattle. Spend the $80 on this box, it'll be worth it, especially with those subs.

I bought this box for a Kenwood system and am extremely impressed. It was not as big as you would think so it will fit in your trunk. For the price you can't beat it for a custom box. Well worth the price and then some if you want the best from a system go with this box or any profesionally ported box the only con is the terminals the plastic nuts make me nervouse and they would be easy to lose. SonicElectronix got you covered for sure if you don't know what your doing ask them for what you think you want it to sound like and they will get you squared away. A huge thanks goes out to SonicElectronix. They know how to put a system together that will be compatible for you.

The only cons about this is the terminals are plastic and can become loose. This however has not effected the sound quility. This box is very heavy duty and sounds outstanding. It matches my interior and was impressed with the craftmanship. It smelled freshly crafted after opening the box!! love it
